Description
Handstück für zahnärztliche Bohrmaschinen Die Erfindung betrifft ein Handstück für zahnärztliche Bohrmaschinen und besteht darin, daß auf die durch Aufispleißen des vorderen Endes der Hauptwelle entstandenen Klemmbacken die vorderen Arme von doppelarmigen Klemmhebeln einwirken, welche <furch Vorschieben einer die Welle umschließenden und mit ihrem vorideren Ende die rückwärtigen Hebelenden unterfassenden und anhebenden Hülse in Wirksamkeit zu treten vermögen.Handpiece for dental drills The invention relates to a Handpiece for dental drills and is that on by splicing of the front end of the main shaft clamping jaws the front arms of double-armed clamping levers act, which <by advancing the shaft enclosing and with its front end, the rear lever ends under-gripping and lifting sleeve are able to come into effect.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigt: Abib. i das Handstück im angespannten und Abb.2 im gespannten Zustande.The drawing shows an embodiment of the subject matter of the invention shown, namely shows: Abib. i the handpiece in the clamped position and Fig. 2 in the tense conditions.
Das den Gegenstand der Erfindung bildende Handstück besteht aus der Achse a, welche an ihrem vorderen Teil an zwei Stellen geschlitzt ist, so daß zwei sich gegenüberliegende Klemmbacken bl und b2 entstehen, welche eine in anderen Handstücken eingebaute Spannzange ersetzen. Die Schiebehülse c ist an ihrem vorderen Ende konisch ausgebildet. Beim Vorschieben dieser Hülse c unterfaßt deren konischer Teil die rückwärtigen Enden der einander gegenüberliegenden, doppelarmigen Klemmhebel d' und d2, welche dadurch angehoben werden, während ihre vorderen Enden, da de Hebel vorn durch den Ring e beweglich gelagert sind, zusammengepreßt werden und so einen Druck auf die Klemmbacken b1 und b2 ausüben, wodurch das Werkzeug zwischen den Klemmbacken b' und b2 festgehalten wird.The handpiece forming the subject of the invention consists of the Axis a, which is slotted at its front part in two places, so that two Opposing clamping jaws bl and b2 arise, which one in other handpieces Replace built-in collet. The sliding sleeve c is conical at its front end educated. When this sleeve c is advanced, the conical part undergoes the rear ends of the opposing, double-armed clamping levers d ' and d2, which are thereby raised, while their front ends, since the lever are movably mounted in front by the ring e, are pressed together and so one Apply pressure on the jaws b1 and b2, placing the tool between the jaws b 'and b2 is held.
